This listing is for a vintage Trident 80B mixing console in very nice condition. The desk has 40 channels of mic/line pre's as well as 24 channels of monitor return w/EQ's. The 1/4" military grade patch bay system was housed externally and wired by Stephen Hasselton (Mastering Lab) The unit has been regularly maintained in a professional recording studio and aside from the first 6 mic inputs (need new transformers) everything else works great. A ton of punk rock legends recorded their albums with this board and when it comes to rock nothing sounds quite like a Trident 80B. Will come with power supplies, meter bridge speakers stands and patchbays racked in a nice KK audio rack
